Description

This example python algorithm saves a workspace to file in ascii format. The algorithm exists for demonstration purposes only; ordinarily SaveAscii should be used instead.

Inputs are a filename and a workspace. The output is a file in the default save directory with the input filename and containing data from the input workspace in ascii format. Bin centers, rather than bin boundaries, are saved.

Usage

Example - save example workspace:

# Load sample workspace
temp_ws_ = CreateSampleWorkspace()

# Use algorithm to save workspace
filename = 'ExSaveAsciiFile.txt'
ExampleSaveAscii(temp_ws_, filename)

# Get the default save path
workdir = config['defaultsave.directory']
filepath = os.path.join(workdir, filename)

# Read and print first 3 lines from file
with open(filepath, 'r') as f:
    print(f.readline()[:-1])
    print(f.readline()[:-1])
    print(f.readline()[:-1])

# Delete the test file
os.remove(filepath)

Output:

# Time-of-flight , Spectrum , E
1
100.0000,0.3000,0.5477
